CHARLES H. LENHARI, OF PLYMOUTH, WISCONSIN.

CHAIR-SE AT.

Specification of Letters atent.

Application filed May 23, 1908. Serial No. 434,454.

To all whom it may concern.'

Be it known that I, OHARLEs H. LENHART, a citizen of the United States, and resident of Plymouth, in the county of Sheboygan and State of Wisconsin, have invented certain new and useful Improvements in Chair- Seats; and I do hereby declare that the following is a full, clear, and eXact description thereof.

My invention relates particularly Vto chairseats that individually comprise a piecedwood frame and a laminated wood or veneer top, said invention consisting in what is herein vset fo'rth with reference to the accompanying drawings and pointed out in claims; its main object being to provide partly hollow` wooden chair-seats having the same general appearance as solid wood chair-seats and which are more economical', lighter and stronger than those of the solid kind, while at the same time they'are not liableto warp or be otherwise detrimentally affected by atmospheric changes.

Figure l of the drawings yrepresents a plan` view of one of my improved chair-seats having the top thereof partly broken away, and

Figs. 2, 3 and 4 sectional views of said seat on planes respectively indicated by lines 2 2, 3-3 and 4--4 in Fig. 1, the cross-brace appearing in Fig. 2, being `broken central of same.

Referring by letter to the drawings, A represents the frame; B the top and C the bot.- tom of a hollow wooden chair-seat in accordance with my invention. The frame is ordinarily of the pieced-wood variety, although it may be otherwise, and the top and bottom are preferably of laminated wood generally known to the trade as veneer.

An important feature of my invention is providing the frame with braces D, E, so disposed as to support the weight and compensate for the strains that ordinarily tend to sag and otherwise detrimentally affect a laminated wood top glued or otherwise fastened to said frame. This bracing of the frame is an important feature of my invention and applicable to laminated wood top chair seats with or without bottoms similar -to the one C herein.

The braces D are transversely of the frame A from side to side of same, and the braces E are set in .between those aforesaid and the front and rear of said frame. All these braces are primarily of the same thickness .of

wood, but for a saddle-top Bsuch as is herein shown, the upper faces of the braces E are shaped to match the opposing depression of said top.

In building up the seat, the top is preferably glued on the frame, and the braces being properly treated with glue, they are one by one rubbed into place, the ones D being first positioned, and good adhesive contact of said braces is had with opposing surfaces of said top and the frame, after which the aforesaid braces are faced off flush with the under side of said frame. Now if the built-up seat is to have the appearance and answer as a substitute for-a solid wood seat, the bottom C is glued onto the frame and braces.

In a built-up apparently solid chair-seat, the unvarnished inner surfaces of its top and bottom are not exposed to atmospheric conditions and consequently said top and bottom have no liability to warp or crack, nor is said seat as a whole liable to warp, as is the case with solid wood seats.

It being possible to utilize low grade wood for the braces, and the top and bottom of the -built-up seat being ordinarily of laminated wood, said seat is more economical than a solid one and it is also much lighter, stronger, and more durable. It is also to be observed that there is dead-air space in the built-up seat comprising the frame, top and bottom, whereby the comfortableness of said seat is enhanced because of the non-conductivity of heat by the same.

I claim: y

1. A chair-seat frame provided with crossbraces and other braces between those aforesaid and its front and rear, and a top secured on said frame in contact with said braces.

l2. A chair-seat frame provided with crossbraces and other braces between those aforesaid and its front and rear, and a top secured on the frame in adhesive contact with the braces.

3. A chair-seat frame provided with crossbraces and other braces between.those aforesaid and its front and rear, a top secured on the frame in contact with the braces, and a bottom underlying said frame and braces.

In testimony that I claim the foregoing I have hereunto set my hand at Plymouth in the county of Sheboygan and State of Wisconsin in the presence of two witnesses.
